RELEASING DEVICE 'FOR CARCOUPLINGS.

Specification of Letters Patent.

Patented Jan. 1, 1916.

Application filed January 1G, 1915. Serial No. 2,510.

ile it known th a t l, lflcwnnn lV. HAn'roUGi-r, a citizen of the United tates of America, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Releasing Device for Car-Couplings,

of which the following is such a full, clear,

and exact description as will enable any one skilled in the art to which 1t appertains to the accompanying drawings, forming rt of'this specification.

lriy invention relates to a releasing device for car couplers and has for its object the production of releasing device which will be as simple as possible in construction. and

which shall be 'durable and edective in operation.

.et further obgect of my invention 1s to provide releasing device which will allow of the necessary niovenent between the coupler head and the body of the car and which. i

at the same time, will secure a substantially vertical pull upon thereleasingpin so as to reduce friction to a minimum. and thus secure the easy operation of'the device.

In Athe accompanying drawings, which illustrate one form of releasing device-made in accordance with my' invention, together with somuch. of a' railway car as is necessary to illustrate the manner of applying the device thereto, Figure 1 is a top plan view 5 Fig. 2 is a front elevation; and Fig. 3 is a side View.

Like marks of reference refer to similar parte in the several views of the drawings.

`5 represents the body of the car and 6 the striking 'block carried thereby.' The striking block is preferably provided with a metal face plate 7 inthe usual manner.

'Projecting through the striking block 6 and the face plate 7 is'a draw bar 8 provided with a coupler head 9. l

10 is a knuckle pivoted at 11 to the coupler head f-and controlled by a locking pin 12 having an eye 13 which engages withl the releasing device which will be hereinafter described.

All of the above parts may be of any usual or wcll-known construction..

rl`he releasing device consists of a rod 15 having a bent portion 16 at the outer end forming a handle and a bent portion 17 at the inner end .forming a fulcrum for lifting the locking pin 12. ,The body 15 of the rod is provided adjacent to the inner end 1i' Le and use the same, reference being had a portion 16 bent slightly out of line with the body 15 so as to be parallel with the end of the car in the normal position of the parts. This portion 18 passes through the eye 13 of the pin 12. The body 15 is also provided adjacent to the handle 16 with a portion 19 bent slightly out of line With the part 15 so as to be parallel'with the part 18. This part 18 engages with a bracket 2O secured to the car by means of l bolts or rivets 21. The opening 22 in the bracket 20 through which the part 19 passes is of slightly greater diameter than the part 19 so as to allow the rod l5 to have a rocking movement in a horizontal plane in order to allow for the necessary movement between the coupler head 9 and the body 5 of the car. The inner end 17 forms a fulcrum for lifting the pin 12 and its tip or point 23 is preferably rounded as shown in F ig. 3. Ars 'best shown in F ig. 3, the rearwardly projecting inner end 17 of the lifterV is normally out of contact with the upper face of thc striking block 6 so that there is no friction between the parts when the coupler head is moved relatively to the'body of the car.l When, however, yit is desired to release the )lock or pin 12, the .handle 16 is moved u pwardly, thus causing the point 23 of the arm 17 to come into'contact with the upper surface of the block 6, thus forming a fulcrum point` for raising the pin 12. As the pin is raised, the end 17, being entirol y unconnected with the block 6, is free to move forward on the upper face of the block so that the pin is raised in a vertical direction without any side pull and thus friction is avoided and easy operation of the device'secured.

In some types of couplers, the locking pin comprising a bearing adjacent to the side of the car, a bearing independent of the coupler head, a rod extending, directly from said first named to the locking pins 'of 'the coupler and unsupported between said points,a11d anfmm axaendinw to Said' second baarng fonil a portion 0I the md 'beyond said pin.
